“…This trend shows a huge potential in fully digitalizing more than 100-year-old X-ray technology. Our research group have invested substantial time in these recent five years to fully develop the digital CNT-based X-ray source in the lab [1][2][3]. The X-ray sources can be both fabricated either using analogue-type filament E-gun or digital-type CNT E-guns [4][5][6].…”

In this paper, we demonstrated the comparison of digital-based CNT and analogue-based filament X-ray sources by taking the X-ray images of ACR mammo phantom for developing the intraoperative specimen X-ray system. The X-ray image of ACR mammo phantom taken at 25 kV 1 mA by filament shows overall the better image quality. However, when X-ray images of phantom were compared at 40 kV 1 mA by both sources, it showed that CNT X-ray source showed better image quality because of Aluminum window.
